I have a Surveyor SV-264 trailer. I have read through the owners manual but I haven't read how to jack up the trailer. I have asked a few people (even employees at the dealer) and have not gotten a good answer. Do you jack up using the frame? Using the axle? I just want to make sure if I have a blow out that I don't do more damage to the frame/axle. I believe the Surveyor has torsion axles so I don't know if that makes a difference.
